Exercise guide
Ab Crunch Machine
The Ab Crunch Machine is a seated strength exercise that uses adjustable resistance to train the abdominals. Once the seat, pads, and handles are set, you curl your torso forward against the machine and return slowly. The supported setup makes it easier to focus on the abs without balancing a free weight.
Training context
Benefits of the Ab Crunch Machine
The machine provides a stable path and makes it easy to adjust the resistance in small steps. This can be helpful when you want direct abdominal work that is simple to track from one session to the next.
Because machine designs vary, take time to adjust the seat and pads before starting. A comfortable setup should allow you to crunch through the torso without pulling hard with the arms or driving the movement with the legs.
Technique overview
Let your abs move the resistance
Start with a light weight and adjust the machine so the handles and pads feel secure. Brace your feet, exhale, and curl your ribs toward your hips using a slow, controlled motion. Avoid yanking on the handles or using momentum. Pause briefly in the crunch, then return until your torso is upright without letting the weight stack slam down.
Treat this as an overview and use a range, pace, and setup you can control.
